CHARGING-CAR.

Y all whom it may Concern:

Be 1t known that we, FRANK D. CARNEY and Riemann V. MCKAY, citizens ofthel United States of America, residing at Steelton, in the county ot'Dauphin and State of Pennsylvania, have invented certain new and usefulImprovementsin Charging-Cars; and we do hereby declare the following tobe a full, clear. and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings. and toletters or figures of reference marked thereon, which form a part ofthis specification. v

Our invention relates to mechanism for sintering ore and other fines,and has for its object to provide a cover for any well-known type ofsintering pan, whiclifshall not only operate as a covery for theignition of the material in the pf'n, but shall alsooperate as a .meansfor charging the pan, and means for leveling thercliargein the panbefore sintering. I

Specifically. the cover is mounted on a car truck operated by suitableelectrical mechy anism. to which current is supplied through a trolleyor otherwise, as will hereinafter be more particularly -pointed out andclaimed.

Referring to the drawings, in which like a plan view of'mechanismembodying 'our invention. Fig. 2 is a side view thereof, having partsbroken away. Fig. 3 is a vertical section on line 3-3 of Fig. Q. showingthe various lever mechanisms in elevation.

nism for quickly and casily placing rthe rover. on the pan, or forremoving it when tiuignition or the sintering operation was completed,and the charging ot the pans. and the leveling of the chargel in thcpans hasl been done manually.

According to our invention we provide a ar carrying the cover, and thecover can be rapidly raised and lowered with respect to the pan when thecar has been run over lsaid pan. The cover is also provided Awith adrop-bottom, for carrying alcharge sullicicnt to lill the pan whendumped, said bottom also acting as leveling 'means for leveling thecharge in the pan y A`n in its dropped position, and also acting. whenraised, as the inclosing cover over the igniting means and pan. The carcarries an electric motor` operated from the trolley or its equivalent,

, projecting below, or at least on a level.l with the dumping bottom.

Asa

-The sintering 'pan A is located between track rails 2 andat such aheight between these. rails that the cover can be easily applied andremoved.

The ear comprises a suitable framework or body 3, of structural iron,provided at one. end with a platform 4 o1ij."wl1i,chI ris mounted thevarious'mechanisms-required forthe operation of the car. In the frame orbody 9,'is'mounted an axle?) and a driven aX'le (3 on the endslofwhichare rigidly se-` cured the car wheels 7. The frame 3 is alsoprovided with transv-'erse members 3 adjacent each end of a cover 10,and on'which are mounted antifriction rollers 8 operating in channelsf)on the cover ll0. Acrossthctop of the frame 3 near each end of the cover-10 are shafts 11 and 12', each provided with two levers 13 rigidlysecured thereto near the sides-of the cover. Each lever 155 isconnect-ed by link '1l to lugs or'ears 15 on the cover. p

The shaft 11 is provided'at one end with a downwardly inclined lever 16.and the shaft 12 i's` provided with an upwardly inclined lever .17.Pivoted on the end of lever 17.'-

Fig. 2, is a rope connect-ion 18, from Vwhich a rod, wire -or rope 19leads to a like conllO nection 20, pivoted to the end of lever 16,whereby both shafts 11v and 12 are caused to operate sinniltaneousl)Ywhen the rope ,19 is drawn. This rope 19 is drawn by means of a ropellwhose rope connection 22 at one end is also pivoted to lever 17, andwhoseA other end is connected to a rope drum 23 on The main drivingshaft 24 has allarge spur gear wheel 31 actuated by a pinion 32 of anelectric motor 33 supplied with cury rent through a trolley. 34. Thelift of the cover 10 need be but a few inches, and it can be raised fromthe posit1on shown in the drawings -by means of the-.ropes 19 and 21when the clutch 27 is thrown, after which it may beheld in its raisedposition by the brake 25, 26, when the clutch is disengaged.

The brake band 26 is connected to a rod 56 which is connected to a crankarm 57 on .a shaft 58 provided with a lever arm .59

operated by a pedal 60, Figs. 2 and 3.

The cover also carries a burner 35 of the type shown in .United StatesPatent No.

1,064,314, granted June 10, .1913. This burner is connected by a pipe36, flexible connection 37 and line 38 to oil tank 39on platform 4:. Theburner 35 and pipe 36 are 4supported by an angle iron 40 extendingacross the middle of the cover. j Air is supplied to the burner througha pipe 41 contained within the pipe 36 and 4o having a flexibleconnection 42 with a line air pipe 43 leading'to a compressed airstorage tank 44, also 'on platform l, and which is supplied withcompressed air througha pipe 415 fronran air compressor 46 driven by anelectric motor 47, also located on platform 4.

The line pipes 3S and 43 are provided with'cut-ofll valves o anda'respectively, located at the platform 1, and actuated by any suitablelever mechanism, indicated at The tops of the airvand oil tanks areconnected by a pipe Z) having` a valvec whereby air pressure is appliedon the surface of the oil in the tank. 39.

The main driving shaft 2l is. provided with a loose chain wheel 4Sarranged to be connected to and disconnected from said .shaft by meansof a clutch 49 operated by a 'rod 50, a bell-crank. lever 51, a link anda hand lever 53.

The bottom of the cover 10 consists of a series of louvers or sectionalbottoms 61, more clearly shown in Fig. 5, each of which is secured on ashaft 62 and arranged at sulicier. heightvabove the bottom edge of thecover so that when the louvers assume the position shown in dotted linesin Fig. 5 to discharge their loads, the lower edges of these louvers orsectional bottoms will be substantially in a plane with the bottom of.

the cover.` Each shaft 62 is provided with an upwardly inclined lever 63at one end thereof and between the frame and the cover and'all of theselevers 63 are connected to a rod 61,. whereby the louvers'l may be'simultaneously operated.

Connected to the rod 64 at 65 is a' rope 66 v struction andv operationto brake band 26,

and is connected to a rod 7l, Fig. `3, which is connected to a crank 475on a rod 76 provided 'with a lever arm 77 that is actuated b v pedal 78,this mechanism being substantially a duplicate of the clutch, drum andbrake mechanism on the opposite end of shaft 2l.

7 9 is a controller, `controlling the sup-ply current to the motor 33.

The louver mechanism or drop bottom for the cover 10 is held raised byrod 611, rope 66, drum 67 and brake 68. y

Thecar is run to the mixing plant, or other source of supply of materialto be sintered,"a11d the cover is loaded with said material, w zich'ispreferably but not necessarily struck off level across the top ofthecover. The clutch -19 is thrown to clutching position so that the motorwill drive the car with the cover suspended in raised position therein.Upon arrivingv in position over the pan A the clutch is disconne'ctedand brake 26 is released, thereby permitting the entire cover 10 withits contained load to be lowered onto the pan A. The clutch 63v is thenreleased, and the weight of the load on the louver bottom 61 will causethe louvers to turndown into the dotted line position shown in Fig. 5.The cover is then slightly raised and traversed ba ck and forth, so thatthe depending louver bottom. 61 will strike the charge level. The extentof this movement need not be greater than the width between the leaves61. The cover 10 is then lowered againonto the pan and the 'louversraised into the .position shown in full lines in Fig. 5. Suction is thenplaced on th`e pan A through its open ends. vThen the valves 0 and a areopened, and compressed air and oil are supplied to the burner 35 andignited. The ignition of the material to be sintered takes place inabout. a minute, 4more or less, after which the supply of fuel and airto the burner is 3130 sinteringthe charge, the air -would iiollow cntoff, the cover'lifted clear of the 'pan, and the ca r 1s drlven again tothe mixing plant for another' clia1'ge,wl1ile the combustion of thecharge in the pan is maintained and Vthe sintering operation completedby the suction at theen'ds of the pan. v Heretofore 1t has beenldifhcult toA place th chargein the sintering -pan so that it would havea uniform compactness. 'hen the pan.-

was vloaded by shoveling .the material into pan from aphopper. T he.result was that when the pan was placed. under suction for the course ofleast resistance through the lessj compacted places and bore through at*'"thesefpoints, leaving a large portion of the charge unsintered. Theproblem of obtainf lng somefpractlcable method of charging these pansthat is sutlicientlyeconomical to .beperformed for commei'clal ,purposeshas occupied the attention of engineers for some time. IVe believe lthatwe have sl'lccessf'ully solved this problem for commercial pur-- poses;instead of obtaining a 'cake from the sintered material. we'obtain acakethat con- 'tains' from 60% to 90% of sintered material, and'v this yisdue to our method of charging,

This 'method consists in' moistening the charge to about the.consistency of molders sand, subdividing it, and dropping all portionsofthe subdivided charge into the pan -fromthesameheight, so that thesame degree of lcompactness will be caused by the one foot, more orless.
